Abstract: An enhancement in disposable packaging for several types of food, made of a relatively hard laminate material, such as a plastic paper card in both sides. A series of cuts and creases form a pyramidal torso box with four upper closing brims. Two of the brims are folded over one another, with the other two likewise folded over one another. The brims comprise edges which present a crease and a tip in hook, respectively, corresponding to complete the closing of the pyramidal box. In addition, two equal triangular-shaped brims are formed in two opposite sides of the box, also assisting in completing the box configuration. In the preferred embodiment, the triangular brims comprise free edges folded by a vertical cut, so that such edges are juxtaposed when the two brims are lifted against the corresponding lateral wall of the box. At such point, each brim receives a soldering line or a thermo-soldered line along the side and upper edges thereof, creating a tight and secure closure and seal of such area.

Abstract: The present invention relates to a foldable carrying handle for a portable lunch-box which is made of plastic and consists of seven pieces which are hingedly interconnected into one-part bar-shaped body. The one-part bar-shaped body includes a cross bar, two upper overlapping pieces, two lower overlapping pieces and two positioning pieces. The cross bar corresponds to the width of the lunchbox and is positioned at the center of the bar-shaped body. The two upper overlapping pieces are symmetrically disposed at both ends of the cross bar. The two lower overlapping pieces are symmetrically disposed at outer end of both upper overlapping pieces. The two positioning pieces having finger-shaped fastener are symmetrically disposed at outer end of both lower overlapping pieces.

Abstract: This invention relates to paperboard containers. Such structures of this type, generally, allow for the container to be formed into a self-locking, pail-like container for holding food stuffs.

Abstract: A single piece container and method for making the same are presented. The container has an opening and a body and includes first and second pairs of opposing covering flaps and a pair of opposing handles. The covering flaps cover the container body opening so as to keep the container contents in place.

Abstract: A carton includes a bottom wall panel, four side wall panels, each of the side wall panels being integrally connected along a fold line to the bottom wall panel thereby defining first and second pairs of opposite side wall panels. Corner portions integrally connect adjacent side wall panels. The corner portions are secured in overlapping pairs against the second pair of opposite side wall panels. Flap members are provided with each of the flap members being integral along a flap fold line with one of the side wall panels of the first pair of opposite side wall panels. Each of the flap members includes foldable portions constructed and arranged to be folded into generally overlapping relation with a central portion of the flap member. Closure members are provided with each of the closure members being integral along a closure fold line with one of the side wall panels of the second pair of opposite side wall panels. Tab structure secures a closure member to an adjacent flap member.

Abstract: A container formed of foldable sheet material including a body of a slightly tapered inverted conical configuration having opposed pairs of closure flaps integrally hinged to the upper rim of the body and foldable to overlie the upwardly directed open mouth of the container. The inward folding of the flaps inwardly flex corresponding portions of the body wall to a generally rectangular configuration adjacent and downward from the rim. The outer flaps interlock by a cooperating tongue and slot. In variations, integral or bonded handles are provided to overlie the closed container. Additional sealing at the defined corners between adjacent flaps is achieved by integrally formed folding gussets.

Abstract: An arched clamshell type carton formed from a one piece blank of paperboard having cut lines and score lines. The bottom of the carton is square, with each of two opposite sidewalls having spaced apart, coplanar ears, each of the latter being semicircular. The other two opposite sidewalls of the bottom are elongated and are each bent around the edges of respective opposite, aligned ears. The ends of these latter walls carry hooks and also handle forming panels, the hooks being each engaged with a respective latching flap positioned between respective pairs of ears.

Abstract: A disposable ice, food or beverage carrier which is fabricated of corrugated fiberboard materials. A single piece of bendable corrugated fiberboard is factory die cut and scored in such manner that it may be easily folded into a container assembly for use by picnickers or other persons requiring a temporary insulative container. The score and cut-line designs disclosed yield a highly durable temporary food container.
